Other Proteins

Human Cluster of Differentiation 19 (CD19), also known as B-lymphocyte surface antigen B4, Differentiation antigen CD19, T-cell surface antigen Leu-12, GenBank Accession No. NM_001770, a.a 21-291, with C-terminal Avi-Tag™ fused to the Fc portion of Human IgG1 and labeled with phycoerythrin (PE), expressed in a HEK293 cell expression system. MW = 59 kDa. This protein runs at a higher apparent M.W. by SDS-PAGE due to glycosylation.

Human NRAS also known as GTPase NRas and NS6, GenBank Accession No. NM_002524, a.a. 2-186, with Q61H mutation and N-terminal His-tag, expressed in a Baculovirus infected Sf9 cell expression system. MW=22 kDa.

Human NRAS, also known as GTPase NRas and NS6, GenBank Accession No. NM_002524, a.a. 2-186, with Q61L mutation and N-terminal His-tag, expressed in a Baculovirus infected Sf9 cell expression system. MW=22 kDa.

Severe acute respiratory Coronavirus 3C-like protease (SARS-CoV 3CL Protease), GenBank Accession No. 1UK3_B, a.a. 1-306(full length), with a C-terminal His-tag, expressed in an E. coli expression system, MW=36 kDa.

Human OX40L, also known as tumor necrosis factor ligand superfamily member 4 (TNFSF4) and CD252, GenBank Accession No. NM_003326, a.a. 51-183(end) with a N-terminal His-Avi-tag, expressed in a HEK293 cell expression system. MW = 23 kDa. This protein runs at a higher MW by SDS-PAGE due to glycosylation.

Severe acute respiratory Coronavirus Spike trimer (S1+S2), with 682-685>A, K986P, V987P, and D614G mutations, Genbank Accession No. MN908947, a.a. 1-1213, with a C-terminal His-tag, expressed in a HEK293 expression system. MW=137 kDa. This protein runs at a higher M.W. by SDS-PAGE due to glycosylation.

Recombinant human KRAS (GTPase), isoform b, encompassing amino acids 2-185. This construct contains an N-terminal His-tag (6xHis). The protein also contains cancer-associated mutation G12C. The protein was affinity purified.

SARS-CoV-2 Spike S1 receptor binding domain (RBD), also known as SARS-CoV-2 Spike 1 RBD, novel coronavirus Spike 1 RBD and nCoV Spike 1 RBD, GenBank Accession No. QHD43416.1, a.a. 319-541 with G476S mutation and with a C-terminal Avi-His-tag, expressed in a HEK293 cell expression system. MW= 28 kDa. This protein runs at a higher M.W. by SDS-PAGE due to glycosylation.

Recombinant human KRAS (GTPase), isoform b, encompassing amino acids 2-185. This construct contains a N-terminal His-tag (6xHis). The protein was affinity purified and was loaded with BODIPY-GDP. Unbound BODIPY-GDP was removed by spin column and the protein is ready for a GDP/GTP exchange assay.
